Abstract

Detecting a packet transmission is disclosed. A first plurality of detection metrics is determined using a first signal having a first synchronization waveform received on a first band. A second plurality of detection metrics is determined using a second signal having a second synchronization waveform received on a second band. The first and second plurality of detection metrics are combined to produce a plurality of combined detection metrics. The packet transmission is detected using at least one of the plurality of combined detection metrics. Detecting a boundary within a transmitted packet is also disclosed. A first symbol of the transmitted packet is received in a band. A second symbol of the transmitted packet is received in the band. The first and second symbols are compared. The boundary within the transmitted packet is detected based at least in part on the comparison of the first symbol and the second symbol and the band. Receiving a signal is also disclosed. A signal received in a first band is amplified. It is determined if the amplified signal satisfies a saturation condition. A change to a second band is triggered based at least in part on the amplified signal satisfying the saturation condition.
